Should I trust her? Should I believe her?

[Andres Ibarra]

Recently my girlfriend of 5 months has been going to her friends house every Friday for the past 3 weeks. They're all girls. Well my girlfriend has been sober of smoking weed for 2 years. recently I had a feeling that she might be doing it again. So i went onto twitter and saw one of her friends saying "damn wind wont let me light it" and "now my fingers burnt". That Friday night I texted her brother and he was just as suspicious as me. So I told him, when she gets home, talk to her and try to find out if she is.So she got home and she was really sleepy, she is never sleepy at 10. So he talked to her before she went to her room and she said she didn't do anything and he said that she was telling the truth. I still had a feeling she was doing it and she lied to him just so he wont ask questions or tell her parents. So I texted her that night saying I just want the truth, You shouldn't be doing this anymore, you're better than that etc etc. She never texted back. So I went over the next day and she walked with me out side. I told her if she did anything and she said"No! Why would I ruin my 2 years of being sober?!" when she said that I believed her. So we went on with our day together and walked to the park. On the way to the park she put her phone in my pocket and forgot about it. After we got home I told her i had to use the bathroom. I went through her messages and saw that she told one of her friends that she did smoke. After that I went back to the living room and didn't look at her in the face. She said "babe what's wrong" I had tears coming to my face and told her to go outside with me. I told her, "why did you do it. Why did you lie to my face" she said "I didn't do it!" So I said "look through your phone" and she started crying. She said "why would you look through my phone! I can't trust you anymore" And I said "You can't trust me? Why would you lie to my face!" she said "because I didn't want to fight about this! I didn't want you to be mad at me!" She looked at me with a dead serious face and said " You have no idea how horrible it is knowing you're friends are smoking and you can't do it." we kept talking and eventually we agreed that we both did something bad. Me for looking through her phone and her smoking. We went back inside and acted like nothing happened. I just really want to know what to do from now on. I love this girl with all my heart. And I'm not saying she is a bad person for smoking either. But the fact that she lied to my face gets me mad and thinking I can't trust her anymore. Until yesterday I trusted her everyday and never had any suspicion. I need advice. What should I do? I don't want her to be with those friends anymore. She used to smoke week 5 to 6 times a week. Maybe she can do it once a month? I need help. I asked her that night saying "from now on I want nothing but the truth, even if it is something I don't want to hear, I'd rather find out the hard way than you lie to me." and she said "Ok I will tell the truth" But is she saying that just to shut me up again like last time?

"Maybe she can do it once a month?"

Well, first of all she will decide what she does. She isn't your property. Like she said she didn't
want any trouble from you for doing it. If a Christian over reacted about me not believing in God, i would just avoid the conversation all together, maybe even suggest that i do believe in God just to shut him up.

She isn't smoking crack, she is smoking a drug that is prescribed to people for use everyday in multiple states. It isn't something to be concerned about if she can moderate her usage.
